世卫组织建议勿用非糖甜味剂控制体重

近日，世界卫生组织发布了一项关于非糖甜味剂的新指南，建议不要使用非糖甜味剂来控制体重，或以此降低非传染性疾病的风险。

证据表明，使用非糖甜味剂对减少成人或儿童的体脂没有任何长期益处。长期使用非糖甜味剂可能会产生潜在的不良影响，例如成人患2型糖尿病、心血管疾病和死亡率的风险增加。

WHO warns against artificial sweeteners for weight loss in new guidance

From: CBS NEWS

People looking to lose weight should skip sugar substitutes, according to new guidance from the World Health Organization.

The United Nations agency said Monday that a systematic review of the available evidence suggests use of non-sugar sweeteners "does not confer any long-term benefit in reducing body fat in adults or children."

It also shows there may be "potential undesirable effects" from the long-term use of these sweeteners, such as an "increased risk of type 2 diabetes, cardiovascular diseases, and mortality in adults."

Replacing sugar with non-sugar sweeteners "does not help with weight control in the long term. People need to consider other ways to reduce free sugars intake, such as consuming food with naturally occurring sugars, like fruit, or unsweetened food and beverages," Francesco Branca, WHO Director for Nutrition and Food Safety, said in a press release. Artificial sweeteners "are not essential dietary factors and have no nutritional value. People should reduce the sweetness of the diet altogether, starting early in life, to improve their health."

The recommendation applies to all people except individuals with pre-existing diabetes, the review says, as assessing this group was simply beyond the scope of the data used.

What artificial sweeteners are bad for you?

WHO's recommendation encompasses "all synthetic and naturally occurring or modified non-nutritive sweeteners that are not classified as sugars" found in manufactured foods and beverages or sold on their own to be added to foods and beverages.

The agency notes common varieties include acesulfame K, aspartame, advantame, cyclamates, neotame, saccharin, sucralose, stevia and stevia derivatives.

This guidance comes months after a study found erythritol, a zero-calorie sugar substitute used to sweeten low-cal, low-carb and "keto" products, is linked to higher risk of heart attack, stroke and death.

Researchers at the Cleveland Clinic studied over 4,000 people in the U.S. and Europe and found those with higher blood erythritol levels were at elevated risk of experiencing these major adverse cardiac events. The research, published in the journal Nature Medicine, also found erythritol made blood platelets easier to form a clot.

In response to those findings, in February, Robert Rankin, executive director of the Calorie Control Council, an international association representing the low- and reduced-calorie food and beverage industry, told CBS News the results are "contrary to decades of scientific research showing low- and no-calorie sweeteners like erythritol are safe, as evidenced by global regulatory permissions for their use in foods and beverages, and should not be extrapolated to the general population, as the participants in the intervention were already at increased risk for cardiovascular events." 

Sugar-free products containing erythritol have been previously recommended for people with obesity, diabetes or metabolic syndrome as ways to manage sugar and calorie intake. Erythritol is one ingredient in the common calorie-free stevia sweetener Truvia, for example.

对于这些发现，卡路里控制委员会（Calorie Control Council）的执行主任罗伯特·兰金（Robert Rankin）在2月份对CBS新闻表示，这些结果“与数十年来的科学研究相矛盾，这些研究表明，像赤藓糖醇这样的低热量和无热量甜味剂是安全的，全球监管机构对它们在食品和饮料中使用的许可就是证明，而且这些结果不应该被推广到一般人群中，因为干预组的参与者已经存在心血管疾病风险增加的问题。”
